IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 93,412, dated August10,1?1869.

.To a/ZZ whom, it may concern:

Be it known that I, NATHAN BUTTLER, of Otterville, in the county ofCooper and State of Missouri, have invented a new and usefnl Improvementin Oultivators; and I do hereby declare thatthe following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure lis a detail sectional view of my improved cultivator, takenthrough the line x x, Fig. 2. Fig. 2 is a front view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved cultivator whichshall be simple in construction and convenient in operation, being soconstructed and arranged that the plows may be readily adjusted to runat a greater or less depth in the ground, and that the plows may beeasily raised away from the ground, when desired, by'a simple movementof the drivers seat; and it consists in the construction and combinationof various parts of the machine, as hereinafter more fully described.

A represents the wheels, which revolve upon the journals of the axle B,to which the tongue C is rigidly attached. The attachment of the tongueC to the axle B should be strengthened with lhounds or braces D, to makethe connection between said parts stronger.

E is a bolster placed upon the upper side of the axle B, and hinged tosaid axle by means of eyebolts F or other suitable hinges.

The rear lower edge of the bolster E is beveled off, so that the saidbolster may be turned back sufficiently to raise the plow away from theground when desired.V

G are the plow-standards, which are secured to the bolster E by loops H,the arms of which loops pass through the bolster E, and are detachablysecured in place by nuts. The upper part of the forward side of theplowstandards G is notched to receive the loops H, so that the saidstandards may be raised and lowered, according to the depth-at which itis desired to havethe plows work in the ground,

by simply loosening the nuts upon the arms of the loops H. Theplow-standards Gare so formed that their rear sides may rest against theforward side of the axle B, so that the draft-strain may be supported bysaid axle. The lower parts of the standards G may be straight, or may beinclined forward at different or at any desired angle, according as itis desired to have the plows work in line, or one in advance of theother.

I are the plows, which may be made in the form of shovel-plows, diamondplows, bulltongue plows, or some of one form and some of another form,as may be desired.

J are arms projecting horizontally in the rear of the bolster E, and theforward ends of which are bent downward, and are securely attached tothe forward side of the bolster E. The arms J are further supported andstrengthened by standards or supports K, attached to the rear side ofthe bolster E, and upon the upper ends of which rest the arms J, asshownin Fig. I. l

L is the drivers seat, which is attached to the arms J in such a way asto slide back and forth freely.

VMis a small platform or foot-rest, attached to the rear part of theaxle B, as shown in Fig. 1. rIhe bolster E is locked,when the plows arein working positions, by the lever N, the lower end of which is pivotedto the axle B, and the upper part of which catches upon a catch, O,attached to the forward side of the hinged bolster E, as shown in Fig.2. v

P are guides attached to the bolster E, upon each side of the standardsG to support said standards against side movement.

By this construction, when the driver wishes to raise theplows from theground to pass obstructions, or for any other purpose,he detaches thelever N, and, by a movement of his body, pushes the seat L back, so thathis weight may overbalance the weight of the plows and raise them fromthe ground. When he desires to have the plows again operate, he rises tohis feet upon a small platform or foot-rest M, and the weight of theplows brings the machine again into working position, in which positionthey are locked by the lever N.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The bolster E, hinged to the axle B, and beveled upon its rear loweredge, substan- 4. An improved cultivator, formed by the combination ofthe Wheel A, axle B, tongue C, hinged bolster E, arms J, sliding seat L,footrest or platform M, and plow-standards G with each other,substantially as herein shown and described, and for the purposes setforth.

NATHAN BUTTLER.
